all thats horse ****, the D35 is a weaker axle but it will handle 31's go for the lift, obviously people have been lifting their cherokees for years and nobody says it swists their "frame" or nothin, its actually a unibody

You friend is either nuts or one of the sheep. He believes every thing he hears.
It is true the D35 is the weakest of the axels available on the XJ. But thaty doesn't mean it's too weak for lifts, lockers and bigger tires, for 99% of the people out there. It means that if you are of the 1% who do HARD CORE wheeling most of the time, you MIGHT want to upgrade. A D35 is strong enough to handle up to a 32" or 33" tire with a locker. I would limit myself to DD and class 7-8 and lower trails. Yes you could handle the occasional class 10 trail, if you are carefull. The the Root cause of most D35 breakage is a heavy right foot applied at the wrong time.

Frame twisting, well this is imposible in an XJ, as the XJ does NOT have a frame. XJ are a unibody chassis, and yes the body will twist and flex. Lifting does NOT cause twisting and flex. It takes some pretty narly wheeling to cause enough flex and twist to be damaging. If you are going to wheel a XJ that hard, you had better be running some major armor and reinforment if you plan to finish a trail anyway.

Your friend is full of it. If you have a 2000 XJ. You have a 8.25 in the rear and a D30 up front. Disregard what cats tell you about these 2 axles. Yes they are weaker to others. But a D44 axle has the same design flaw in the front as the D44. You'd have to do some crazy wheeling and horrible driving to brake the inner axle. It's the outer you'll more likely come across issues.
Personally I think 4.5" - 5.5" of lift is ideal. You're still low, but can weezle in some 33's tires. Hell, if you wanted to. You could replace the stock axles with bigger. Such as Dana 44's or Dana 60's. But for the most part your talkin serious dough. Or you can replace the factory inner and outers with cromoly. It's said that cromoly makes it about 30% stronger.
I run a 4.5" Rusty's lift which I got 5.25" of lift after it settled. 5 years into the lift. No issues. 33" BFG M/T KMII's. Minor trimming. Still get good flex.
The unibody is the "weak link" in the XJ. It's not as thick of steel. Which is why they make frame stiffiners. When welding on a XJ frame. You just use lower heat to not comprimise the integrity of the frame.
My one word of advice for ya. Always cross reference information. There's alot of people out there with an opinion and no true experience. I've found this with the guys that have the money for a new Rubicon and never owned an XJ.
